The application of cold recycling machine milling in road stabilized soil has the characteristics of high construction efficiency, good construction quality assurance, and high degree of mechanized construction, and has good operational effects in stable soil construction. How about the progressiveness performance of cold recycling machine milling construction technology? Below is an analysis of the cold regeneration machine rental manufacturer for you:
施工效率
Construction efficiency
（1）冷再生機工作原理是采用冷再生技術，它是將需要改建或大修的路面，經過翻挖回收、破碎、篩分，并加入適量的穩定劑（本項目穩定劑為32.5水泥），在常溫情況下重新拌和，形成具有一定路用性能的再生混合料，用于鋪筑路面基層或底基層的整套工藝技術。
(1) The working principle of the cold recycling machine is to use cold recycling technology. It is a complete process technology that involves digging, recycling, crushing, screening, and adding an appropriate amount of stabilizer (32.5 cement in this project) to the road surface that needs to be rebuilt or overhauled. It is then remixed at room temperature to form a recycled mixture with certain road performance, which is used for paving the road surface base or subbase.
冷再生機在銑刨時采取與水車直連的方式，推動水車前行施工。綜合按每分鐘行走10-15m計算，平均每天的施工斷面可達800m，按照本項目道路設計水穩層寬度9.5m計算，即每天可完成7600m2。
The cold regeneration machine adopts a direct connection with the water truck during milling to drive the water truck forward for construction. Based on a comprehensive calculation of 10-15m walking per minute, the average daily construction section can reach 800m. According to the design water stability layer width of 9.5m for this project's road, 7600m2 can be completed per day.
（2）路拌機的馬力一般是360/400,平均每天施工量約5500m2即580m。路拌機基層穩定前必須對穩定路面進行灑水悶料，等穩定土含水量大于佳含水量的1-2%時路拌機才能開始作業，但在天氣干熱地區，水分散失過快，這樣就加大了悶料的難度，同時難以保證施工進度。
(2) The horsepower of the road mixer is generally 360/400, and the average daily construction volume is about 5500m2 or 580m. Before stabilizing the base layer of the road mixer, it is necessary to sprinkle water and fill the stable road surface with materials. Only when the moisture content of the stabilized soil is greater than 1-2% of the optimal moisture content can the road mixer start operating. However, in dry and hot weather areas, the water loss is too fast, which increases the difficulty of filling materials and makes it difficult to ensure construction progress.
（3）平地機的主要作用是平整路面，若使用平地機對基層拌合施工，會影響機械的施工效率，產生窩工，同時在平地機拌合料時要不斷加水而保證含水量，也很難保證能將混合料拌合均勻，施工難度大。
(3) The main function of the grader is to level the road surface. If the grader is used to mix the base course, it will affect the construction efficiency of the machinery and cause idleness. At the same time, when the grader is used to mix the materials, it is necessary to constantly add water to ensure the water content. It is also difficult to ensure that the mixture can be mixed evenly, and the construction is difficult.
（4）攤鋪機施工穩定土必須建立拌和站，而且攤鋪寬度也必須增加至少1m。比如：項目線路全長154公里，若是運輸距離過遠，攤鋪機肯定會出現窩工現象，影響施工進度。
(4) A mixing station must be established for paver to construct stabilized soil, and the paving width must be increased by at least 1m. For example, the total length of the project line is 154km. If the transportation distance is too far, the paver will certainly slow down and affect the construction progress.
比如假設運輸距離為10KM，每臺車運8m3（壓實）料，從拌和站裝滿料運到現場卸料后再返回預計需要1小時，每天可往返8趟，10臺車每天可運輸640m3（8*8*10），按攤鋪10.5m（9.5m+1m）寬度計算，即每天可完成406m。
For example, assuming a transportation distance of 10KM, each vehicle transports 8m3 (compacted) of material, and it is expected to take 1 hour to transport the full material from the mixing station to the site for unloading before returning. It can take 8 trips per day, and 10 vehicles can transport 640m3 (8 * 8 * 10) per day. Calculated based on a width of 10.5m (9.5m+1m) for paving, 406m can be completed per day.
施工質量
Construction quality
（1）對于水穩層來說，層厚和佳的含水量是不容易掌握的，冷再生機連接水車，推動水車施工，冷再生機后配有專人檢測銑刨深度和含水量大小，在發現銑刨深度或含水量不達標的情況下，冷再生機駕駛員可以在駕駛室內直接通過電腦調整銑刨深度和供水量，另外冷再生機駕駛艙外還配有水閥開關，可以手動調節水量大小，保證其滿足銑刨深度并處于佳的含水量狀態。
(1) For the water stable layer, it is not easy to grasp the layer thickness and optimal water content. The cold regeneration machine is connected to the water truck to drive the construction of the water truck. After the cold regeneration machine, a dedicated person is equipped to detect the milling depth and water content. If the milling depth or water content is found to be not up to standard, the cold regeneration machine driver can directly adjust the milling depth and water supply through a computer in the driver's cab. In addition, the cold regeneration machine is also equipped with a water valve switch outside the driver's cabin, The water content can be manually adjusted to ensure that it meets the milling depth and has an optimal water content state.
冷再生機銑刨后壓路機即進行封水工作，確保水分不散失。這樣就可以保證終壓時不出現“鼓包”、“彈簧”等現象。另外由于水泥終凝時間較短（一般在4小時左右），而冷再生機工序銜接緊密，在銑刨完一段后（約100m）平地機就可以精平、終壓，銑刨一段完成一段，可以確保施工質量。
After the cold regeneration machine is milled and planed, the roller immediately performs sealing work to ensure that water is not lost. This can ensure that there are no "bulges", "springs" or other phenomena during the final pressure. In addition, because the final setting time of cement is relatively short (generally about 4 hours), and the cold recycling machine processes are closely connected, the grader can finish leveling and final pressing after one section of milling (about 100m), and the construction quality can be ensured by finishing one section of milling.
（2）路拌機在施工時平均每50-100m會產生一個施工接縫，施工接縫若不能妥善處理對路基的危害會很大，同時路拌機施工時水分散失過快，而在補水的時候會出現水分不均勻也，同時增加了施工時間，會嚴重影響碾壓后的基層質量。
(2) During construction, the road mixer produces an average of one construction joint every 50-100m. If the construction joint cannot be properly treated, it will pose a great threat to the roadbed. At the same time, the water loss during the construction of the road mixer is too fast, and uneven water may occur during water replenishment, which increases the construction time and seriously affects the quality of the compacted base layer.
（3）平地機拌合混合料時很難保證達到佳含水量，也不能保證拌合混合料的均勻度，造成碾壓不實，出現干濕“彈簧”現象，不能滿足施工要求而造成返工。
(3) When mixing the mixture with grader, it is difficult to ensure the good water content and the evenness of the mixture, which causes the compaction not to be compacted and the phenomenon of dry and wet "spring", which cannot meet the construction requirements and causes rework.
（4）攤鋪機攤鋪水穩時若運輸距離過遠，在運輸途中會大大散失水分，到現場后含水量不能達標，對這樣的料源攤鋪后在補水會增加施工時間，更會出現水分過多或過少現象造成碾壓不實，出現“彈簧”，而水泥也可能失效，不能保證水穩層強度，影響路基質量。
(4) If the transportation distance of the paver is too far when paving the water stabilized layer, the water will be lost greatly during the transportation, and the water content will not reach the standard after arriving at the site. The construction time will be increased when the water is replenished after paving such material sources, and the phenomenon of too much or too little water will also occur, which will cause the compaction to be not solid, resulting in "spring", and the cement may also fail, which cannot guarantee the strength of the water stabilized layer, affecting the quality of the subgrade.
